“…The residues after all the sequential extractions contained only 75 mg P kg j1 of dry matter. The observed greatest P amount presented in the HCl fraction is consistent with numerous previous reports (Codling, 2006;Dail et al, 2007;Dou et al, 2003;He et al, 2006b;Turner and Leytem, 2004). A different P distribution pattern in poultry litter and manure reported earlier (Sharpley and Moyer, 2000) was apparently caused by lack of organic P measurement in the HCl fractions.…”

“…As little difference in P concentrations were observed in the same fractions with the three binding agents (lignosulfonate, urea formaldehyde resin with catalyst, and water), we attributed the changes in P distribution in these granular products to the drying (heating) effect during the granulation. Previously, Dail et al (2007) observed a similar bilateral trend of poultry manure P change during drying. We also observed the differences in the assumed values and P concentrations in fractions of poultry litterYandYbiosolidYtogether granulated products (i.e., PLUB and PLUBDCD).…”

“…On the other hand, granulation had a part of NaOH-extractable P transformed to more stable HCl and recalcitrant residual P in granulated litter, and even HCl-extractable P to residual P in the granulated litter/ biosolid mixing products. We assume that the heating is the major cause of the transformation as such similar changes have been observed in drying poultry manure (Dail et al, 2007). Under extreme conditions of ashing, most (80% or so) P in poultry litter is transferred into the HCl fraction (Codling, 2006).…”

Land application of biosolids and poultry litter can benefit crop production by providing phosphorus (P) and other nutrients and organic matter. However, the bioavailability of applied P in those waste materials is directly dependent on the presence of specific P forms. In this study, we comparatively examined the P forms in biosolids and broiler litter by sequential fractionation (i.e., H 2 O, 0.5 M NaHCO 3 , 0.1 M NaOH, and 1 M HCl fractions) coupled with enzymatic hydrolysis. Extractable P in broiler litter was found in the order of HCl 9 H 2 O 9 NaOH 9 NaHCO 3 . Biosolid P was found in the four fractions in the following order: HCl 9 NaOH 9 NaHCO 3 9 H 2 O. Correlation analysis indicated that P was coextracted with Ca, Mn, Zn, Fe, and Al, but not Mg. Whereas most P was Ca bound in broiler litter, Al, Mn, and Zn played more important roles in metal P species in biosolids. The relative abundance of P species was determined to be inorganic P 9 hydrolyzable organic P 9 nonhydrolyzable organic P in each fraction. Compared with the P levels in the samples stored in a freezer, storage of the broiler litter sample at room temperature transformed part of the phytate P in the HCl fraction to other forms, resulting in more labile P in the H 2 O fraction. Granulated products of poultry litter and biosolid could be used as off-farm nutrient sources. Data in this work show that granulation transformed moderate NaHCO 3 -and NaOH-extractable P bilaterally to labile water-soluble P and stable HCl-extractable P in the granulated poultry litter but did not remarkably change the distribution of H 2 O-, NaHCO 3 -, and NaOH-extractable P in granulated products containing both poultry litter and biosolids.

Phytate (inositol hexaphosphate) has been identified as a major organic phosphorus (P) form in soil, animal manure, and other environmental samples. Although a number of methods are available for quantitative isolation and determination of phytate, they are time-consuming and not amenable to routine analysis. We developed a simple, rapid method for enzymatic determination of phytate in animal manure. Animal manure was extracted by H 2 O, 1 M hydrochloric acid (HCl), 0.1 M sodium acetate (NaOAc, pH 5.0) with or without 0.05 M ethylenediaminetetraacetate (EDTA), and 0.25 M or 0.5 M sodium hydroxide (NaOH)-0.05 M EDTA. Extracts were diluted (1/10-1/150) and adjusted to pH 5.0 in sodium acetate buffer. The diluted extracts were then incubated at 37 uC for 1 h in the absence and presence of fungal 3-phytase (PHY) and potato acid phosphatase (PAP). Enzymatic hydrolyzable organic P was calculated as the difference in inorganic P (P i ) between the mixtures with and without enzymes. Our data indicated that enzymatic incubation of properly diluted and pH-adjusted HCl or NaOH/EDTA extracts released phytate P.

Consequently, we recommend this method of combining PAP and PHY for quantifying phytate P. Additional research is being conducted to verify the effectiveness of this method for general use across a wider range of soils and manures.

“…However, as for the comparison between undried and dried sludge, this could be because other opposing mechanisms are more important after addition to soil. Furthermore, we cannot explain the otherwise general trend of decreasing water‐extractable P with temperature, which appears contrasting to previous studies ( Dail et al, ; poultry manure). Nonetheless, as these differences were not apparent after mixing with the soil, we assume that they would not have any major influence on the value of sludge as P fertilizer.…”

Thermal drying of sewage sludge implies sanitation and improves practical handling options of the sludge prior to land application. However, it may also affect its value as a fertilizer. The objective of this study was to assess whether thermal drying of sewage sludge, as well as drying temperature, affects plant P availability after application to soil. The experiment included dewatered sewage sludge (20% DM) and thermally dried sewage sludge (95% DM) collected at a Danish wastewater treatment plant, as well as laboratory oven‐dried (70, 130, 190, and 250°C; DM > 95%) subsamples of the dewatered sludge, and a triple superphosphate as a reference. Plant P availability was studied in a 197 d soil incubation experiment, with sampling for Diffusive Gradients in Thin films (DGT) and water extractable P (WEP) analyses over time, and in a pot experiment with spring barley (Hordeum vulgare L.). In both experiments, thermal drying reduced P availability, as shown by 37 and 23% lower DGT and WEP values, respectively, and a 16% lower P uptake by barley in the pot experiment. The specific drying temperature did not appear to have much effect. Overall, our results suggest that thermal drying of iron‐precipitated sewage sludge is not an optimal treatment option if the aim is to optimize plant P availability.
